This invention relates/to ajountain pen and one object of the invention is to provide a pen the barrel of lwhich is adapted to receive a sealed ink cartridge or capsule and the 'Q' pen stock of which has means foropening said cartridge when the barrel is attached to the pen stock, thus permitting ink to flow to the pen point. r v

' A further object of the invention is to provide a cartridge having a removable closure Aand a pen .stock having means for engaging that closure and moving the same out of the opening in the cartridge when the barrel kof the pen is attached to the pen stock. A

35 A further object of the invention is to provide such a pen in which the closure for the cartridge will be supported by the pen stock after it has been removed from' the opening in the'cartridge and `Will be reinserted in that cartridfre when the pen stock is detached from the barrel. i

A further object of the invention is to provide an ink cartridge which will be simple in its construction and which may be easily filled and sealed. i

Other objects of the invention will appear as the device is described in detail.

In the accompanying drawings Fig. 1 1s a longitudinal sectional view of a pen em- 39 bodying' my invention; partly broken away, andwith a part of the 'pen stock inelevation; Fig. 2 is a similar view showing the barrel detached from ythe pen stock and the sealed cartridge partly inserted in the barrel; Fig. 3

is a rear end view of the pen stock; and Fig.

4f is a plan view of the-sealed end ci` the cartridge. lr A .e

In these drawings I have illustrated one embodimentv of my invention but it will be 4 understoodthat this has been chosen for the purpose of illustration only and that the device may take various forms without departing from the spirit of the invention.

As here shown, the'pen compri-ses a pen supporting and feeding portion 5 which may be conveniently termed the pen stock, and detachably connected with the Ipeli stock is a tubiilar member or barrel 6. n the present instance, the inner end of the perk stockis 5 providedwith internal threads andthe inner opening, 9 and ispreferably screwed down end of the barrel is provided with external threads, as shown at 7, whereby the two parts may be connected with and disconnected from one another. In order that the pen may be quickly and easily filled without liability of getting ink on the lingers I havel provided a cartridge adapted to be lledwith y ink and sealed and then inserted'in the barrel of the pen, the 'sea-ling closure for the cartridge being of such a character that it may be engaged and removed by a part connected with the pen stock when the barrel is screwed onto the pen stock. As here shown, the cartridge comprises a tubular member 8 closed at one end and adapted'to fit within the barrel 6 of the pen. t its upper end the cartridge is provided with a relatively large opening 9 through which it may be filled and w through which the ink may escape to the pen stockwhen the cartridge is assembled in the pen. The opening 9 is preferably of uniform diameter throughout its length and is screw threaded. After the cartridge has been iilled a screw threaded closure 10 is inserted in the until its outer surfaceiis ush with the end of the cartridge. When the cartridge is to be placed in the pen the/barrel'is detached from the pen stock, the cartridge`inserted in the barrelfand the barrel then again attached to the pen stock. The pen stock is provided with astud 11 adapted to engage the closure 9 and screw the same through the opening and beyond the inner end of the opening, so as to completely remove the same from the opening. Preferably the closure is provided in its outer side with la screw threaded socket 12 and the stud ll .hasits end portion screw threaded to enter the socket l2. The socket is arranged centrally of the cartridge and the stud 11 is arranged axially of the pen stock. When the cartridge has been'inserted in the barrel and the barrelis screwed onto the pen stock the stud 11 will be screwed into the socket 12 and when it reaches the lower end of the socket "will cause the closure to rotate therewith in a directionto screwthe saine out of the opening 9 andy to sup ort the same in spaced relation to the end wa of the cartridge., In the form illustrated the 10o threads in the opening 9 and on the closure 10 are so arranged that the closure will be moved inwardly and supported beyond the inner end of the opening, as shown in Fig. l. The stud 11 may be connected with the pen stock in any suitable manner but, in the present instance, the pen stock is providedwith a transverse ypartition 13 which carries the stud 11 and which is provided With openings 14 to permit the ink to flow from the cartridge to the pen point. Any suitable mea/ns may be provided for holding the cartridge against rotation within the barrel of the pen, and, as here shown, the lower end of the cartridge is provided with a rib 15 adapted to enter a groove 16 in the closed end of the barrel. When the barrel is removed from the pen stock the closure 10 will be a ain screwed into the opening S) and, if no o struction isoii'crcd to its movement, may be screwed entirely through that opening and remain on the stud l1. This, however, would necessitate the removal of the closure from the stud with the likelihood of getting ink on the fingers. I therefore prefer to provide means which will cause the stud to be unscrewed from thel closure, leaving the latter in the opening in the cartridge. Inasmuch as the closure must be, screwed into the opening/ from the outer side thereof when the filled cartridge is scaled I `have provided a stopwhich may be secured to the end of the cartridge after the closure hasbeen placed in poy sition and which will overlie the closure to prevent the same from bein moved outwardl'y beyond the end wall of t e cartridge. As here shown, this stop is L-shaped in form, as shown at 17, and one arm thereof is inserted in a socket in the end of the cartridge adjacent to the opening 9 and i-s preferably cemented therein, the other arm of the stop extends laterally beyond the end of the opening so as to overlie the closure. Thus when the barrel is detached from the pen stock the closure willrbe screwed into the opening until it contacts with the stop and thel stud will then be screwed out of the closure, thus leaving the closure in the cartridge. If the cartridge is empty it may be removed and thrown away and a new cartridge inserted without danger of getting ink on the fingers. If the cartridge contains ink which it 1s desired to preserve it is properly sealed when the barrel is separated from the en .stock so that the ink will not be spilled. his arrangement also permits ofinterchangeably using inks' of different color with one pen, as one cartridge can be readily sealed and removed and another cartridge substituted therefor.

While I have shown and described one embodiment of my invention I wish it to be `an ink cartridge removably su ported in said barrel and having an opening 1n that end adjacent to said pen stock, a closure for said opening adapted to be inserted therein from the outer side thereof, and means carried by said pen stock to en agesaid closure and move the same from sai opening and beyond one end thereof when said pen stock is attached to said barrel.
